SPECIFICATION forming part of Letters Patent No. 461,436, dated October 20, 1891.

Application filed June II 1889- Serial No. 313,914. (No model.)

To all whom it may concern:

Be it known that I, EDWARD WILLIAM MAC- KENZIE -HUGHES, of Chicago, Cook county, Illinois, have invented a new and useful Impf'ovement in Locomotive-Tender Trucks, of which the following is a full, true, and exact description, reference being had to the accompanying drawings. v

This invention relates to an improvement in metallic locomotive-trucks, in which the support is carried directly by springs upon the side frames themselves; and it consists in making the part corresponding to the kingpin of pressed steel and of providing the same with a cylindrical bearing, also of pressed steel, through which the same may operate.

. My inventionwill be readily understood from the accompanying drawings, in which- Figure 1 represents an elevation, Fig. 2 a longitudinal section, and Fig. 3 a plan View, of my improvement.

The side frames of the truck may be of any desired arrangement; but I prefer to make them of pressed steel, as shown at A.. I prefer, likewise, to make the transom B of pressed steel. My improvement relates to the center pin and surrounding cylindrical bearing, as clearly shown in Fig. 2. This center pin C is made of a cylindrical body of pressed steel hating the shape indicated andworking in the bearing or surrounding cylinder D, likewise made of pressed steel. The shape of the lower part of the center pin C allows of 'the rocking of this center pin within the bearing D, while the same can move freely up and 5 3. A center pin for trucks, formed of a cy- 5o lindrical body of pressed steel, the neck or upper portion of which is smaller than the lower portion, substantially as described.

4. The combination of the pressed-steel center pin C, the neck or upper portion of 55 which is smaller than the lower portion,with the pressed-steel cylindrical socket D, substantially as described.

'In testimony whereof I have signed my name to this specification in the presence of 60 two subscribing witnesses.

EDWARD .WILLIAM MACKENZIE-HUGHES.
